Eran Kutner commented on HBASE-3996: ------------------------------------ Thanks for the feedback @stack ! Will take some time to get to it but I definitely will. As for a patch, I actually used the 0.90.3 sources, not through svn, but I'll try to make a patch out of it. Is it OK to create the patch against a branch or do you want it for trunk? > Support multiple tables and scanners as input to the mapper in map/reduce jobs > ------------------------------------------------------------------------------ > > Key: HBASE-3996 > URL: https://issues.apache.org/jira/browse/HBASE-3996 > Project: HBase > Issue Type: Improvement > Components: mapreduce > Reporter: Eran Kutner > Fix For: 0.90.4 > > Attachments: MultiTableInputCollection.java, > MultiTableInputFormat.java, MultiTableInputFormatBase.java, > TableMapReduceUtil.java, TableSplit.java > > > It seems that in many cases feeding data from multiple tables or multiple > scanners on a single table can save a lot of time when running map/reduce > jobs. > I propose a new MultiTableInputFormat class that would allow doing this. -- This message is automatically generated by JIRA.
